Bulla, Bulla!
The situation is tense. The fate of empires hangs in the balance. If you sit back and wait for your enemy to bring it to you you are going to lose. As things stand, if you put everything you've got into one massive effort to defeat the Hun you just might find victory.
I (Roman's) invade a large island occupied soley by the Persians. Xerxes dusted the Indians and the Zulu long ago and has had a chance to develop the entire mini continent. He has well over 100 Mech Inf, about 30 Tanks, 15 or so Bombers and other assorted units. Of course he has Rails.
The Granda Marina has blown the goats out of a Persian coastal city (4 CVs and 8 BBs with 8 DDs will do that). 16 Marines are poised to assault the city. 4 are lost in overcoming the defenders (about 4 MechInf, 1 Inf). The Transports sail in and disembark. This lands 8 Artillery, 8 MechInf and 16 Tanks along with 12 Marines in the newly Roman city. All Fortify (except the expended Marines) to withstand the hurricane which is sure to follow. The Roman AirForce massively reinforces the invasion area.
The hurricane ensues. Only, instead of an all-out assault to immediately push me back into the sea, about 30 MechInf surround the city and begin pillaging. 
I occupy my next turn by popping off some of the adventuresome Persian MechInf, and RushBuy an Airport. All Jet Fighters set to AirSuperiority.
On Xerxes turn, the hurricane commences. But it is only a brisk gale. Our Jets shoot down a few Persian Bombers. About 8 Persian Tanks expend themselves probing against the fortified MechInf.
On our turn, we Airlift in reinforcements, and probe out of the city.
On Xerxes's next turn the Persians destroy our small probe force and again attack our positions at the city. He commits enough to do damage, but holds back forces still. Our AirForce shoots the h*ll out of the Persian Bombers.
Our next turn, more probe out. RushBuy the AirPort again.
And so it goes. It took me much too long to get to the next Persian city. Interestingly, I underestimated the AI, and escalated my forces much too slowly. But finally, after shifting massive Tank and MechInf forces in, the forces of Rome are making progress.
But, the point is that Xerxes should have nailed the entire invasion force right there on turn 1. 30 Tanks and 50 MechInf should have been more than enough to annihiliate 16Tanks, 8 MechInf and 12 Marines. No?
I understand why it is so now. The game must be fun for even the casual gamer. Making invasions nearly impossible would not be fun for many people. But the fact is the enemy was barging in the gate, and the defenders had more than enough to destroy them. In fact the situation cried out for a Bum Rush. Oh well.

The AI bombards fairly well using its navy and bombers, but needs to use artillary rather than just keeping it around for defense, and the odd unit every one in a while.
AI needs to upgrade better. in my current game, I am in a joint operation w/ most of the world against the aztecs, I'm attacking w/ tanks (which noone else has yet) but the ai is assisting w/ immortals, archers, longbowmen, etc. The AI should have upgrading in its operational hierarchy, or at least place a higher priorty on it.
Does the AI use spies very frequently? I think I have only caught one or two trying to infiltrate, of course, I don't try to ferret them out, so my empire may be riddled with them.
There you go, some of the most obvious holes in the AI's warmaking ability.

The situation of the Bum Rush is on Emperor, Large Map, Continents. 12civs. WarmClimate. Increased TechCost. 8 Turn MinimumResearchTime. |
Ah, then sorry about the previous post. I was speaking in more general terms, game long tactics, not specific situations.
Does the AI change tactics the higher the level? I have heard that level increases only gives benefits to the AI, doesn't teach new tricks, right?
What I was referring to occured while playing on monarch.

nye, if I follow your thought processes, you are trying to help Soren develop a kick-ass military AI. Kudos, I agree.
The examples you've used thus far are with late-game military... not my forte (yet). But I'll try to contribute...
First off, let me say that I agree with an implicit premise of yours: on Monarch and higher, the AI should be able to demolish the human player, unless the human uses every bit of wit, wisdom, strategy and tactics available. I love the idea of a "Soren's Revenge on the Whiners" level.
Without a formal study, here are some of the aspects of that advanced military AI that I think need to be addressed:
* Concentrated / overwhelming force: No more dribs and drabs, please. If the AI is going to come after me, don't send in forces in groups of 2 or 4, in series. The AI should choose an objective, and stack at least 10 offensive units, use an appropriate approach (hills / mountains), and open a can of kick-ass on me.
* The algorithm for combat avoidance is too simplistic... don't let a human strike force into the heart of the AI empire.
* Don't start GWs in key military production cities.
* Don't send Settlers to the front.
* Use arty. Protect it.
* More barracks when faced with a warfare-oriented game. My elite / vet Immortals get bored cutting up regulars.
* More forts on key strategic positions.
* Understand and avoid "killzones." This is almost an exploit for me, although there is historical precedent.
* Firaxis needs to develop a black-white algorithm; there are certain situations when TOTAL military commitment is called for... throw the pots and pans, for Christ's sake!
* Increase aggression for all AI civs, period.
I don't think the military AI needs that much work; I've had my share of multiple stacks of 4 Legions showing up in force. But some tweaking would help.

Whats ironic about the settler carnage is that it is almost exactly what many players do, raze and build own city. unfortunately the AI does this when on the defensive, after its own city is razed, it tries to repopulate the area, leading to quick death. If it could be trained to only do this offensively, like after it has secured a couple of squares around the razed city and then defend it, it would be much more effective and entertaining to play against.

Also, the AI should drop off troops by boat or paradrop onto strategic & luxury resources, and have said troops pillage & fortify to deny their foes access to those resources. They could also attempt to bombard the roads away, but that would require a far larger investment of aerial or naval forces.
This would work better near the coastline or borders with the nation the AI is at war with, obviously.

I know a way to make the AI have the balls to get rid of your invasion forces....
I went into the editor and checked the boxes "OFFENSE" as well as "DEFENSE" under Infantry and Mech Infantry.
The AI will use these as offensive units quite often when they have to - they'll send their tanks at you first but then the infantry come in.
I was playing the world map and I (Persia) launched a massive invasion of the East Coast of North America (Britain) with about 17 transports loaded with Infantry and Artillery. I managed to take a tiny city in Florida and I also got one where New England would be, and lastly I took over their capitol which was right on the coast. This was before Motorized Transportation.
Well, the AI was Communist and I upped the draft limit to 6 (come on, Stalin really made use of it) and the Brits were just coming out of annhiliating the Aztecs so they had plenty of draftees over there as well. The AI also had railroads.....
Well, stacked in their capitol I had 18 artillery and at least 25 infantry of various types - mostly veteran, but a few elite and conscript thrown in. City was heavily damaged from artillery so it was size 1 (was 24 before my battleships started hitting it hahaha).
The AI attacked.... first with their cavalry, but when they all died they just sent WAVES of infantry at me. I killed 2 or 3 for every one that I lost, but sure enough they liberated all of their cities in ONE turn. On my next turn the rest of my invasion force just tried to turtle itself and hold on for dear life so I could get reinforcements in, but then the AI used that big stack of captured artillery to smash the hell out of my big stacks of infantry and then went wild sending their infantry against me. I took another city in the boonies of Northern Canada and instead of using artillery against their men I used it all just pounding on their roads and railroads so the massive infantry army couldn't reach me.
All in all it basically turned into what I thought would be an easy invasion into a massive war - the AI lost at least 150 infantry I would expect but they completely annhilated my invasion force and captured all my artillery - they got a great leader almost every turn as well, and formed armies with them it seemed.
Later in this game I finally wiped them out - (Right of Passage agreement with 4 tanks next to EVERY one of their cities does the trick)
But then it became my goal to take out France (they were located in South America and the Southwest of North America). We were already in a nuclear war...
So what I did was I sent a big invasion towards Panama so I could sever their empire in two - I bombed the hell out of every road and railroad in Central America and had workers constructing forts for my Mech Infantry to hold onto the ground.
On their turn they started the march of the massive army sent to wipe out my beachead. I was planning on nuking their cities with my two tactical nukes but then I noticed the HUGE force marching up from the south and the HUGE force marching down from the North. Each one had over seventy troops in them....
KABOOM KABOOM - two nukes drop down and wipe out half of each pile - the French military is now about 2/3 its previous size in just one turn. I killed about seventy units with two nukes - it was beautiful.
So the AI can be manipulated to be a real bastard with its attacking infantry, but it can also be really romped because of it as per my example in France.
Change it as you will, but I find that it does make the AI give you a harder fight - especially in the Industrial age. Before tanks come out the ideal attack unit is probably infantry because of their good defense while cavalry can get whupped. The AI wont attack with infantry because its labeled as a defenseive unit, so I decided to make it both OFFENSE and DEFENSE. Try it, it works.

hehe, sounds like an interesting idea, will have to try it out. Since infantry has a 6 attack rating, the same as cavalry, they can be used legitamately as offensive weapons. I don't remember the attack for the mech infantry. wow This would also make it much tougher to grab cities or retake cities, as there would be a huge amount of defensive units already on site for the AI. sounds like the mid-to-late game would turn into WWI, trench warfare-Its not so bad when the AI sends cav waves and a few infantry, since cav are so (relatively) weak on defense, but infantry in mass quantities at the front....damn sounds tough

The AI needs to learn to protect its units. It does so relatively well with Settlers in the early game, but I've picked off more Longbowmen than I can count on my scientific calculator. The annoying little "strategy" of producing a Longbowman when under siege and using it to counter-attack is cute at first, but really easy to adapt to.
One way of doing this would be to let the AI determine which, if any, of its units are "within reach" at the end of any given turn. If a unit would end its turn within reach the opponent's units, then it should "reconsider" the value of that particular move. I know I make this consideration all the time. "Reconsidering" would involve 1) determining if the unit ends up stacked with a good defensive unit, 2) calculating whether the move is worth it in the first place (eventually, capturing Workers is simply not worth it), and 3) checking the types of opposing units that are within reach.
Example: Babylon is under siege by 2 Immortals, 1 attacking from the North, 1 from the South. Babylon's garrison consists of 1 Longbowmen and 1 Pikemen. The Immortal to the North is at 1 health, but is backed up by some Horsemen 2 tiles away. The Immortal to the South is at full health, but has no backup.
Which Immortal would you choose to attack with the Longbowmen? I think most of us would agree that the one to the South is the right choice; it is relatively easy pickings, and there is no possibility of losing the Longbowmen in a counter-attack. Sadly, the AI would pick the North Immortal, because it's an easier battle.
This problem sort of goes away when the AI gets fast units (but even then it makes suboptimal decisions). In general, the AI's movement patterns are highly exploitable.

The only problem I have seen with my change is that sometimes the AI attacks when it shouldn't - like, if all it has is a conscript infantry fortified in a city and then it builds another one, it will send that second one out to attack your units if you are close by. I guess he should concentrate a bit more on defense but I've been playing like this for awhile now and all in all I think it makes the AI's a bigger challenge.
Just today I upped the infantry attack to 8, to make them better than cavalry and this makes infantry attacks more feasible even.
Mech Infantry attack at a 12 (same as a tank I believe) so it makes them good for it too - they defend at an 18 so even if its Mech vs Mech the attacker isnt at that much of a disadvantage. Before Modern Armor comes out Mech Infantry are the best units since they attack at the same of a tank and defend really well.

Basically you're suggesting that all archer-type units have a Movement of 2, with the restriction that the second move can't be an attack move. Interesting idea, although it would require a complete rework of all other units to maintain game balance. My suggestion is to improve that AI with the units currently available. Which solution is simpler is debatable.

Attacking costs a minimum of 1 movement point.

It would also be ideal for scenarios in some circumstances.
